@seb Cool, but I'm always a bit worried when the pinout diagram is not consistent with the actual board... Missing the 433 MHz antenna connector on the LoPy 4. Also, you should make it clear that 3V3 is an output, not an input.

The pinout is the same for all modules so the pins should remain the same between all of our modules. The only thing to be careful of is pins that are used for the lora radio and the cellular radio on the FiPy other than that if you just need GPIO they should all be ok.
